I'm planning to flush the brake fluid this weekend. The 4M wagon does not have ASR. I've got the CD's and it seems a pretty straight forward job. I plan on using a SpeediBleeder which says to use 15 psi. The MB CD says use 2 bar - closer to 30psi any thoughts?
Also the CD warns not to siphon the reservoir below 10mm of fluids so as to protect from introducing air into the system. I've heard other advice that says to siphon all the fluid from the reservoir and clean out any residue with a lint free rag. Both methods have their upside. Any recommendations?
Happiness is a well stocked
